Jax and his twin sisters are getting kittens! The new four-legged members of the family will be coming home any day. And Fort Builders, Inc., has a new project...pet forts! Together, they know they can come up with the purr-fect hangout for the tiny felines. But they hit a major snag in their testing phase. None of the forts they test out is quite right. Can the team manage to build the best pet palace imaginable in time for the kittens' arrival?
